Help with buying the right cam?
 

I have a 96 tahoe with the 5.7 in it, I'm looking to put a cam in it, more for sound rather than the performance gains. I found one that I liked in a silverado with a 4.8 in it and was wondering if the same cam would fit in my 5motor. Its a lunatai 221/221 .558 112 lsa. here is a link to the video -http://www.youtube.com/watch?v=SHj-QCKUSbg
I was also wondering where i might be able to purchase one.

Thanks!
